Section 1 Assembly and Setup
Tractor RequirementsThis cutter is designed for tractors with a minimum PTOhorsepower rating of 50 HP and maximum of 150 HP.
! CAUTION!Do not over speed PTO or machine damage may result. Thiscutter is designed to be used with a tractor using a 540 or1,000 rpm rear PTO but not both.
Specifically, each cutter is equipped for only one mode ofoperation. Do not attempt to operate a 540 PTO cutterwith a 1,000 RPM PTO tractor. Do not operate a 1000RPM PTO cutter with a 540 PTO tractor. Note that manytractors provide both 540 and 1,000 RPM PTO modes.Check your tractors manual to determine your exact con-figuration.
Before You StartRead and understand the owners manual for your cutter. Abasic understanding of how it works will aid in the assem-bly and setup of your cutter.
Before attempting to assemble the cutter use the followingas a check list. Having all the needed parts and equipmentreadily at hand will speed up your assembly task and willmake the job as safe as possible.
❑ Check for fasteners and pins that were shipped with thecutter. Note: All hardware coming from the factory hasbeen installed in the location where it will be used. If a partor fastener is temporarily removed for assembly reasons,remember where it goes. Keep the parts separated.
❑ If a pin, bolt or other part has been removed, and youare unsure where it is used, use the parts section to iden-tify it. Be sure the part gets used in the correct location. Bydouble checking while you assemble, you will decreasethe chance of using a bolt incorrectly that may be neededlater.
❑ Have a fork lift or loader along with chains and safetystands that are sized for the job ready for the assemblytask.
❑ Have a minimum of 2 people at hand while assemblingthe cutter.
❑ Check to see all nuts are tightened. See “Torque Val-ues Chart” page 24 for additional torque specifications.

b. Shorten inner and outer guard tubes equally.
c. Shorten inner and outer sliding profiles by thesame length as the guard tubes.
d. Proper overlap is a minimum of one-half thelength of each tube, with both tubes being of equallength.
e. Round off all sharp edges and remove burrs.Grease sliding profiles.
9. Route cylinder hoses through hose support loop andconnect to tractor remote outlets. Refer to "HydraulicPlumbing" on page 9 for proper hookup. If the tractorbeing used does not have three pair of supply outlets,an optional control valve kit is available from yourdealer.
10. Cycle the hydraulic system by raising and lowering thecenter deck cylinder and the wing fold cylinders. If op-eration is sluggish, it may be necessary to purge thesystem of trapped air.
! DANGER!Hydraulic fluid under pressure can penetrate skin. Wear protec-tive gloves and safety glasses or goggles when working with hy-draulic systems. Use a piece of cardboard or wood rather thanhands when searching for hydraulic leaks. If hydraulic fluid isinjected into the skin, it must be surgically removed within a fewhours by a doctor or gangrene may result.

Operating Check ListIn addition to design and configuration of equipment; haz-ard control and accident prevention are dependent uponthe awareness, concern, prudence and proper training in-volved in its operation, transport, maintenance and stor-age of equipment. Before beginning to operate yourCutter, the following inspection should be performed.
! WARNING!The following operating procedures should be carried out bythe tractor operator. Other persons should be cleared of thearea even during cutter setup. cutter operation should bestopped when in the vicinity of other persons.
Refer to Figure 2-1:1. Raise the center deck to sufficient height to disengage
the transport link (#1) . Remove the transport link pin(#2), lower the link arm, then replace the link pin to thestorage position.
2. Inspect the wing blade carriers and blades prior tolowering the wings. The wing deck blades may be-come locked together (overlapped) when the wingsare raised to transport position. Operating the cutterunder such circumstances will result in severe deck vi-bration. Inspect the wing decks for a locked blade con-dition prior to power-on operation. Use a pry bar orother tool to separate the blades if necessary.
3. The automatic wing latches on each wing must be re-leased prior to lowering the wings. If the wing latchhandles cannot be moved, it may be necessary toraise the wings to the fully closed position. Releasewing latch and then lower the wings to full-down posi-tion.

Section 5 Maintenance and Lubrication
MaintenanceProper servicing and adjustment is the key to the long lifeof any farm implement. With careful and systematic in-spection, you can avoid costly maintenance, time and re-pair.
For safety reasons, each maintenance operation must beperformed wiht tractor PTO disengaged, the cutter low-ered completely to the ground or on safely supportedblocking, tractor engine shut off and ignition key removed.
1. After using your cutter for several hours, check allbolts to be sure they are tight.
2. After transporting your cutter for several hours, checkall wheel lugs, bolts and nuts to be sure they are tight.Always maintain proper air pressure in the tires.
Service Cutting Blades1. Both blades on each dishpan should be sharpened at
the same angle as the original cutting edge and mustbe replaced or reground at the same time to maintainproper balance in the cutting unit.
IMPORTANT: Replace blades with genuine Land Prideblades only. If one blade is to be replaced, the matingblade {on the same carrier} must also be replaced.
2. Both blades on each dishpan should weigh the same af-ter sharpening.
3. When replacing or sharpening the cutter blades, exam-ine bolts and hardware for excessive wear and replace ifnecessary.a. Torque blade bolt lock nut to 450 ft. pounds. An ex-
tended cheater bar may be required to achieveproper torque.
b. Carefully check the cutting edges of the blades in re-lation to the blade carrier rotation diagram below toensure correct blade placement.
! CAUTION!Installation of the longer blades on the wing decks will cause animmediate operating hazard.
NOTE: Check tightness of bolts periodically, usingthe “Torque Values Chart” on 24 as a guide.
NOTE: Do not remove any more material than nec-essary when sharpening blades.

1. Tighten all 4 nuts uniformly until the spring load is lowenough that the clutch slips freely with the PTO en-gaged.
2. Turn nuts fully back. Clutch is ready for use.
Storage1. At the end of the working season or when the cutter
will not be used for a long period, it is good practice toclean off any dirt or grease that may have accumulat-ed on the cutter and any of the moving parts. It may benecessary to scrape off compacted dirt from the bot-tom of the deck, then use a garden hose to thoroughlyclean the surface.
2. Check the blades for wear and replace if necessary.See "Maintenance & Lubrication".
3. Inspect the cutter for loose, damaged or worn partsand adjust or replace if needed.
4. Lubricate as noted in "Maintenance & Lubrication"beginning on page 19.
5. Repaint parts where paint is worn or scratched to pre-vent rust. Aerosol Buckskin touch-up paint is avail-able from your dealer. Order Land Pride part #821-011C.
6. Replace all damaged or missing decals.7. Store the cutter inside if possible. Inside storage will
reduce maintenance and make for a longer cutter life.
